Subject: [PATCH] Added a constructor that allows us to be a drop-in
 replacement for our superclass and implement a reasonable toString() so that
 if setLogTimers() is enabled, our timers will at least have reasonable
 output. Swing's own timers will still be cryptically logged like so: "Timer
 ringing: javax.swing.Timer@12022b7"
